The song during the end credits is ''A Hero Comes Home,'' sung by Idina Menzel, a Broadway actress who has starred in such shows as Rent and Wicked. She has also appeared in the movie adaptation of Rent (2005).

Q

Why is the entire movie CG, not live-action or live action+CG?

A

Computer-generated images allowed the director, Robert Zemeckis, far more freedom than live-action filming would permit. Zemeckis has already made an all-CG movie, The Polar Express (2004), and knows its benefits. For this film, they include:- camera moves that would not otherwise be possible;- greater control over the art direction;- greater ability to convincingly age the main character, who must grow fifty years over the course of the story;- keeping costs down;- the relative ease of creating 3-D images: once a scene is built for one 'eye', the other eye's view can be created by repositioning the virtual camera and re-rendering; and- images that look especially good in 3-D processes, such as IMAX or Real D.
